The word "EXIT" shall have letters having a width not less than 2 inches (51 mm) wide, except the letter "I," and the minimum spacing between letters shall be not less than 3/8 inch (9.5 mm). Signs larger than the minimum established in this section shall have letter widths, strokes and spacing in proportion to their height.
The word "EXIT" shall be in high contrast with the background and shall be clearly discernible when the means of exit sign illumination is or is not energized. If a chevron directional indicator is provided as part of the exit sign, the construction shall be such that the direction of the chevron directional indicator cannot be readily changed.

Credit 3 - Innovation and Design (ID):

Exceptional Performance


Energy & Atmosphere 

According to the U.S. Department of Energy, buildings use 39% of the energy and 74% of the electricity produced each year in the United States. The Energy & Atmosphere category encourages a wide variety of energy-wise strategies: commissioning; energy use monitoring; efficient design and construction; efficient appliances, systems and lighting; the use of renewable and clean sources of energy, generated on-site or off-site; and other innovative measures.


Materials & Resources

During both the construction and operations phases, buildings generate a lot of waste and use large quantities of materials and resources. The Materials & Resources category encourages the selection of sustainably grown, harvested, produced and transported products and materials. It promotes waste reduction as well as reuse and recycling, and it particulary rewards the reduction of waste at a product’s source.


Innovation in Design

The Innovation in Design category provides bonus points for projects that use innovative technologies and strategies to improve a building’s performance well beyond what is required by other LEED credits, or to account for green building considerations that are not specifically addressed elsewhere in LEED. This category also rewards projects for including a LEED Accredited Professional on the team to ensure a holistic, integrated approach to the design and construction process.

FAQ about photoluminescent exit and path marker signs


NightBright USA Product Line:

How long does it take to charge the product?

It only takes a few minutes of bright lighting for an initial quick charge, but it takes about one hour of exposure to a cool light source such as ambient daylight, fluorescent, LED, mercury vapor or metal halide for a full charge at the installation site.

How long will the product glow?

When fully charged, the product will emit enough light for effective path marking for several hours. The darker the area, the easier it is for the human eye to perceive the light emitting from the signage.

How long will the product last?

If properly used indoors in compliance with the installation instructions, the typical life expectancy of the aluminum backed EXIT signs is beyond 30 years. Per UL924 standard for Emergency Lighting, photoluminescent exit signs do not have to carry an expiration date.

Is this product code compliant?

Yes. The NightBright USA product meets the required codes for emergency evacuation and egress path marking signage. Our product line qualifies under the required provisions of the UBC and IBC as approved by the International Code Council.

What is the product warranty?

NightBright USA Photoluminescent Aluminum products have a 30 year limited warranty on their Photoluminescent properties when installed indoors.

What makes the product glow?

NightBright USA uses a patented technology to apply a photoluminescent pigment to our sturdy aluminum signs.

Is the product radioactive?

Our product is not radioactive. The photoluminescent effect is accomplished through the use of non-radioactive, non-toxic pigment powder which is applied to our aluminum signage.

How do you install the product?

Exit signs are to be affixed onto walls, doors or ceiling by means of tamper proof screws. When using tamper proof screws it may be also appropriate to use in addition an adhesive such as Liquid Nails. If the sign is supplied with frames for ceiling or wall installation, the frames are to be installed prior to placing the sign in the slot supplied and then affixed by means of set screws provided. Path marker signs may be installed using Liquid Nails or an equivalent adhesive.
